1) Same level as the felt boxes
2) Shouldn't be many problems with stock ride height
3) No problems
4) No problems

Hope that helps!

2) With stock suspension, would i clear standard size speed bumps?
3) Slanted driveway issues?
4) Anyone drive at high speed, any noted impacts on air flow

I live in Minnesota where the roads are pretty rough, lots of dips etc.. pulling into parking lots. Just don't want to buy one and trash it three days later. Any additional insight would be appreciated.
